drm/amd/display: Guard against setting dispclk low for dcn31x
[WHY]
We should never apply a minimum dispclk value while in
prepare_bandwidth or while displays are active. This is
always an optimizaiton for when all displays are disabled.
[HOW]
Defer dispclk optimization until safe_to_lower = true
and display_count reaches 0.
Since 0 has a special value in this logic (ie. no dispclk
required) we also need adjust the logic that clamps it for
the actual request to PMFW.
